corrosion in panel enclosure

[John Dirks Jr]

This corrosion was only in the bottom portion of the panel. There was a very poor gutter downspout arrangement just above this panel on the exterior. This is also the northwest wall which gets most of the wind driven rain.

Could moisture seeping through the block wall cause this corrosion? Is that the most likely cause here?

Sounds logical to me,that definately calls for replacement [:-bigeyes

Yeah, I could have poked my finger through it if I tried.

That's why they mount 'em on plywood here (well, most of 'em). The ones that are installed directly on the foundation usually look like that.

Hi Bill

I thought mounting them on some sort of plywood and not directly to a foundation wall was a code requirement.

always see them done this way in Quebec

It's hard to tell from a partial shot, but I would expect corrosion from condensation to be pervasive, not just heavy on the bottom.

I was thinking the same thing, just not as well written.[]

There is rust all over the inside of that panel. I can easily imagine enough condensation forming that it runs down and pools at the bottom. I bet the water heater and HVAC were rusty too.

Here's the whole panel. I looked close at the SEC to see if water was comming in there but could not conclude anything.

If you're trying to determine if it's coming from the SEC then did yiu check the weatherhood outside to see if it is not broken?

You could be getting wind driven rain down the conduit.

Just a guess

Looks like a leaker to me.

See the gutter downspout extension? Its the perforated kind that gets used as drain tile. Wrong material for a downspout extension.

Screw mounting holes drilled in the block will make the water intrusion path that much easier.
